Commencing with real battles, actions and characters, each scenario has been carefully constructed to reveal how at points of decision a different choice or minor incident could have set in motion an entirely new train of events altering history forever. What if Sherman was stalled outside Atlanta, and Lincoln lost the crucial 1864 election? Or if Stuart's Cavalry at Gettysburg arrived in time to give Lee the freedom of operation he lacked in reality? These and many more convincing scenarios are played out against the dramatic and colorful backdrop of this critical and bloody era of American history.
